Oligosaccharides contain:

Correct answer: C. 2-9 Monosaccharides

  • A. Two Monosaccharides
  • B. No Monosaccharides
  • C. 2-9 Monosaccharides
  • D. Numerous monosaccharides

Explanation

Oligosaccharides are carbohydrates that, upon hydrolysis, yield between 2 to 9 monosaccharide units. This distinguishes them from monosaccharides, which do not hydrolyze further, and polysaccharides, which yield many monosaccharides. Therefore, the correct answer is that oligosaccharides contain 2-9 monosaccharides. The other options are incorrect because they either describe a subset (disaccharides) or a different type of carbohydrate (polysaccharides).

About Biological Molecules

The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
